Use in patients with renal insufficiency: Dosage should be reduced in patients with creatinine clearance less than 51 mL/min as scheduled as follows. (See Table 2.)
Meropenem (MEROMAX 500/MEROMAX 1000) is cleared by haemodialysis; it is recommended that the unit dose (based on the type and severity of infection) is administered at the completion of the haemodialysis procedure.
There is no experience with peritoneal dialysis.
Use in patients with hepatic insufficiency: No dosage adjustment is necessary in patients with impaired hepatic function.
Use in the elderly: No dosage adjustment is required for the elderly with creatinine clearance values above 50 mL/min.
Use in children: For children over 3 months and up to 12 years of age the recommended dose is 10-20 mg/kg IV every 8 hours.
In children over 50 kg weight adult dosage should be used.
In meningitis the recommended dose is 40 mg/kg IV every 8 hours.
Febrile episodes in neutropenic patients-the dose should be 20 mg/kg every 8 hours.
Mode of administration: Intravenous bolus injection: Intravenous bolus injection over approximately 5 minutes.
Meropenem (MEROMAX 500/MEROMAX 1000) to be used for intravenous bolus injection should be constituted with sterile water for injection (5 mL per 250 mg Meropenem (MEROMAX 500/MEROMAX 1000)).
This provides an approximate concentration of 50 mg/mL.
Constituted solution are clear, and colorless or pale yellow.
Intravenous infusion: Intravenous infusion over approximately 15 to 30 minutes. Meropenem (MEROMAX 500/MEROMAX 1000) for intravenous infusion may be constituted with compatible infusion fluids (5 to 200 mL).
Overdosage
Should an overdose occurs, the patients should be treated symptomatically.
Contraindications
Meropenem (MEROMAX 500/MEROMAX 1000) is contraindicated in patients who have hypersensitivity to this drug.
Special Precautions
As with other beta-lactam antibiotics, rare hypersensitivity reactions have been reported.
Before therapy with Meropenem (MEROMAX 500/MEROMAX 1000) is instituted, careful inquiry should be made concerning previous hypersensitivity reaction to beta-lactam antibiotics. If an allergic reaction occurs, the drug should be discontinued.
Prolonged use may occasionally result in overgrowth of nonsusceptible organisms.
Pseudomembranous colitis has been reported with nearly all antibiotics, including Meropenem (MEROMAX 500/MEROMAX 1000), and may range in severity from mild to life-threatening. It is important, therefore, to consider this diagnosis in patients who present with diarrhea subsequent to the administration of any antibiotics.
After diagnosis of pseudomembranous colitis has been established, therapeutic measures should be initiated.
Effects on Ability to Drive and Use Machines: There is no evidence to suggest that Meropenem (MEROMAX 500/MEROMAX 1000) may have an effect on a patient's ability to drive or operate machinery.

Action
Pharmacology: Pharmacodynamics: Meropenem (MEROMAX 500/MEROMAX 1000) is a carbapenem antibiotic for parenteral use, that is relatively stable to human dehydropeptidase-1 (DHP-1) and therefore, does not require the addition of an inhibitor of DHP-1.
Meropenem (MEROMAX 500/MEROMAX 1000) exerts its bactericidal action by interfering with vital bacterial cell wall synthesis.
The ease with which it penetrates bacterial cell walls, its high level of stability to all serine β-lactamases and its marked affinity for the Penicillin Binding Proteins (PBPs) explain the potent bactericidal action of meropenem (MEROMAX 500/MEROMAX 1000) against a broad spectrum of aerobic and anaerobic bacteria.

The following susceptibility ranges have been established for meropenem (MEROMAX 500/MEROMAX 1000). (See Table 1.)
Pharmacokinetics: A 30 minutes intravenous infusion of a single dose of Meropenem (MEROMAX 500/MEROMAX 1000) in healthy volunteers results in peak plasma levels of approximately 11 μg/mL for the 250 mg dose, 23 μg/mL for the 500 mg dose and 49 μg/mL for the 1 g dose.
However, there is no absolute pharmacokinetic proportionality with the administered dose both as regards Cmax and AUC. Furthermore, a reduction in plasma clearance from 287 to 205 mL/min for the range of dosage 250 mg to 2 g has been observed.
A 5 minute intravenous bolus injection of Meropenem (MEROMAX 500/MEROMAX 1000) in healthy volunteers results in peak plasma levels of approximately 52 μg/mL for the 500 mg dose and 112 μg/mL for the 1 g dose.
Intravenous infusions of 1 g over 2 minutes, 3 minutes and 5 minutes were compared in a three-way crossover trial. These durations of infusion resulted in peak plasma levels of 110, 91 and 94 microgram/mL, respectively.
After an IV dose of 500 mg, plasma levels of meropenem (MEROMAX 500/MEROMAX 1000) decline to values of 1 μg/mL or less, 6 hours after administration.
When multiple doses are administered at 8 hourly intervals to subjects with normal renal function, accumulation of meropenem (MEROMAX 500/MEROMAX 1000) does not occur.
In subjects with normal renal function, meropenem's elimination half-life is approximately 1 hour. Plasma protein binding of meropenem (MEROMAX 500/MEROMAX 1000) is approximately 2%.
Approximately 70% of the administered dose is recovered as unchanged meropenem (MEROMAX 500/MEROMAX 1000) in the urine over 12 hours, after which little further urinary excretion is detectable.
Urinary concentrations of meropenem (MEROMAX 500/MEROMAX 1000) in excess of 10 μg/mL are maintained for up to 5 hours after the administration of a 500 mg dose. No accumulation of meropenem (MEROMAX 500/MEROMAX 1000) in plasma or urine was observed with regimens using 500 mg administered every 8 hours or 1 g administered every 6 hours in volunteers with normal renal function.
The only metabolite of meropenem (MEROMAX 500/MEROMAX 1000) is microbiologically inactive.
Meropenem (MEROMAX 500/MEROMAX 1000) penetrates well into most body fluids and tissues including cerebrospinal fluid of patients with bacterial meningitis, achieving concentrations in excess of those required to inhibit most bacteria.
Studies in children have shown that the pharmacokinetics of Meropenem (MEROMAX 500/MEROMAX 1000) in children are similar to those in adults. The elimination half-life for meropenem (MEROMAX 500/MEROMAX 1000) was approximately 1.5 to 2.3 hours in children under the age of 2 years and the pharmacokinetics are linear over the dose range of 10 to 40 mg/kg.
Pharmacokinetic studies in patients with renal insufficiency have shown the plasma clearance of meropenem (MEROMAX 500/MEROMAX 1000) correlates with creatinine clearance. Dosage adjustments are necessary in subjects with renal impairment.
Pharmacokinetic studies in the elderly have shown a reduction in plasma clearance of meropenem which correlated with age-associated reduction in creatinine clearance.
Pharmacokinetic studies in patients with liver disease have shown no effects of liver disease on the pharmacokinetics of meropenem (MEROMAX 500/MEROMAX 1000).
